Regarding damaged people.
As for the ones who don't know they are damaged or don't want to heal, yeah, let them go, however, there are damaged people who are aware they are damaged and want to heal.
These people should not be left on their own, they deserve as much love as the next.
I can't decide whether solitude is the right way.
No man is an island, yet there are people who do live in solitude and are happy.
I find that my head can go up my backside if I am alone too much, which is why I like to be with people at times, not all the time.
I remember others have problems and challenges too, I feel good that some people can open up to me and feel helped by me, so, I might have problems but some nights I can go to bed feeling I have helped someone by being with them and listening to them, or even suggesting things which they may, or may not want to take up.
Have you thought of volunteer work with troubled people, youth etc?, you can come home on a night and be in solitude and also feel like you have helped someone.
